CMKP cylindrical self-healing low-voltage shunt capacitors are designed for power factor correction of electrical equipment in 50Hz or 60Hz low-voltage power systems. They are suitable for conventional local compensation and centralized automatic compensation, capable of reducing reactive power loss and improving voltage quality, and are energy-saving products strongly recommended by the state. This product complies with the standards: GB/T 12747.1-2017 and GB/T 12747.2-2017.
1. Altitude: ≤2000mAmbient temperature category: Temperature class -25/C, minimum temperature -25℃, maximum temperature (not exceeding 50℃; the 24-hour average temperature shall not exceed 40℃; the annual average temperature shall not exceed 30℃). The capacitor shall operate under well-ventilated conditions.
2. Maximum allowable humidity: 90% RH
3. After the capacitor is disconnected from the power supply, it must be ensured that the residual voltage of the capacitor drops to 10% of the rated voltage before it can be reconnected. Normally, this period is approximately ≥200 seconds; therefore, a controller with forced time delay for reconnection after disconnection shall be selected. This restriction does not apply to capacitors using equipotential switching controllers.
